The point is, OLE is a Microsoft "technology", so it's really the other way around. OLE only works on Micrsoft and Microsoft compliant software products. Technically, it works with certain applications and codebases that implement an interface named IDispatch.
Unfortunately, from what I can see, Wordpad really has no interfaces derived from IDispatch, which means no OLE (someone please correct me if I'm wrong).
I ask again, though, what are you thinking of doing? Perhaps there is another way around it that a few here could suggest.
